When replacing the existing sensor
IMPORTANT
•
If two or more sensors are used, the
same number of AC transformers (24 V
AC power supply) as the sensors are
required.
Do not share the 24 V AC transformer.
If replacing the existing products with the sensors
(including mixture of existing sensors) , please
check whether the AC transformer (24 V AC) is
shared or not.
Note: For the DC power supply, it is the same as installing new-
ly. (Fig. 17.)
